AI Technical Summary
In existing photovoltaic brackets, the angle between the component steel cable and the side column is fixed at 90 degrees and cannot be adjusted, resulting in a bending angle of the component steel cable at the base plate of the bracket, making it impossible to apply prestress, resulting in stress concentration and tearing problems.
An angle-adjustable flexible bracket side column rigging connection node is designed. By applying force to the end of the finished rigging through a force-applying component such as a jack, the angle between the component steel cable and the side column is adjusted to generate prestressed component steel cables. The rotating seat adjusts the angle accordingly to keep the component steel cables in a straight line and avoid stress concentration.
The prestressing of the component steel cables is achieved, stress concentration is avoided, and the component steel cables are ensured to be clearly stressed and directly transmitted in a straight line, thus preventing the formation of kinks and improving the adaptability and stability of the bracket.

Abstract
Description
Technical Field
[0001] This utility model relates to photovoltaic brackets, specifically to a flexible bracket side column rigging connection node with adjustable angle. Background Technology
[0002] With the large-scale application of mountain photovoltaic power stations, higher requirements have been placed on the adaptability of photovoltaic support systems. Mountain flexible support systems have different requirements for the angle between the component steel cable and the side column according to different terrain conditions and array arrangements. Currently, the component steel cable and the side column are generally at a 90-degree angle, and the angle cannot be adjusted. This is not suitable for photovoltaic arrays with special angle requirements for component steel cables. If a side column cable connection node with an incompatible angle is used, the component steel cable will form a bending angle at the support base plate, which will prevent the component steel cable from being prestressed, causing stress concentration in the component steel cable. As a result, the internal force of the component steel cable will not meet the design requirements, and the component steel cable will tear. Therefore, there is an urgent need for a flexible support side column cable connection node with an adjustable angle to solve the above problems. Utility Model Content
[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an angle-adjustable flexible support side column cable connection node to solve the problems mentioned in the background technology. This utility model has a reasonable structure, can adjust the angle, and has a good effect on preventing stress concentration of component steel cables.
[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: an angle-adjustable flexible support side column rigging connection node, comprising:
[0005] The side column has a support base plate at its top. A pair of support plates are symmetrically arranged on the top of the support base plate. A rotating seat is rotatably arranged on the pair of support plates. A pre-fabricated rigging is arranged on the side of the rotating seat away from the support plate. A component steel cable is inserted through the pre-fabricated rigging, passing through the rotating seat and placed between the pair of support plates. A force-applying component for applying prestress to the component steel cable is connected to the end of the pre-fabricated rigging.
[0006] Furthermore, the force-applying component is a jack.
[0007] Furthermore, a rotating groove is provided through the side wall of each pair of side columns;
[0008] The rotating seat includes a pin installed inside the rotating groove. A pair of side plates are symmetrically arranged on the side wall of the pin, which are placed on both sides of a pair of support plates. An end plate is provided between the pair of side plates.
[0009] Furthermore, the finished rigging includes a wedge anchor set on the side wall of the end plate, a jacking pipe is set on the side of the wedge anchor away from the end plate, and a compression anchor is set on the side wall of the jacking pipe.
[0010] Furthermore, a first through hole is provided on the side wall of the end plate, and a second through hole is provided on the side wall of the pin shaft. The component steel cable passes through the extrusion anchor, the jacking pipe, the clamp anchor, the first through hole, the second through hole, and a pair of support plates in sequence. The axis of the first through hole coincides with the axis of the second through hole.
[0011] Furthermore, a first reinforcing plate is symmetrically arranged between a pair of support uprights and support base plates, a second reinforcing plate is symmetrically arranged between a pair of support uprights and support base plates, and a partition plate is symmetrically arranged between a pair of support uprights above the rotating groove.
[0012] Furthermore, a second limiting plate is provided between the tops of a pair of support plates, an inclined surface is provided on the sidewalls of a pair of support plates, and a first limiting plate that fits against the inclined surface is provided between a pair of support plates and the support base plate.
[0013] Furthermore, a pair of column ear plates are symmetrically arranged on the side wall of the column, and each pair of column ear plates has a connecting hole on its side wall.
[0014] Furthermore, a support groove is provided through the side wall of the side column, which is connected to the top of the side column. The support groove is provided with a support ear plate for supporting the base plate. The side wall of the support ear plate is provided with an installation hole placed below the finished rigging.
[0015] According to the present invention, an angle-adjustable flexible support side column rigging connection node applies force to the end of the finished rigging by applying force through the force-applying component, thereby pre-tensioning the component steel cable and generating prestress in the component steel cable. The finished rigging and rotating seat will automatically adjust their angles as the component steel cable is tightened, thereby adjusting the angle between the rotating seat, finished rigging, component steel cable and side column according to different terrains. This ensures that the component steel cable, rotating seat and finished rigging are always kept in a straight line, making the structural force clear and the force transmission direct. It also prevents the component steel cable from forming an angle at the support base plate at the top of the side column, avoiding stress concentration in the component steel cable.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0026] like Figure 1 As shown, this utility model provides a technical solution: an angle-adjustable flexible support side column rigging connection node, comprising:
[0027] A side column 6 has a support base plate 3 on its top. A pair of support plates 1 are symmetrically arranged on the top of the support base plate 3. A rotating seat 10 is rotatably mounted on the pair of support plates 1. A pre-fabricated rigging 9 is mounted on the side of the rotating seat 10 away from the support plates 1. A component steel cable 13 passes through the rotating seat 10 and is positioned between the pair of support plates 1. A force-applying component is externally connected to the end of the pre-fabricated rigging 9 to apply prestress to the component steel cable 13. This design applies force to the end of the pre-fabricated rigging 9 by using the force-applying component, thereby applying prestress to the component steel cable 13. Pre-tensioning is performed to generate prestress in the component steel cable 13. The rotating seat 10 will automatically adjust its angle as the component steel cable 13 is tightened, thereby adjusting the angle between the rotating seat 10, the finished rigging 9, the component steel cable 13 and the side column 6 according to different terrains. This ensures that the component steel cable 13, the rotating seat 10 and the finished rigging 9 are always kept in a straight line, making the structural force clear and the force transmission direct. It also keeps the component steel cable 13 in a straight state and prevents the component steel cable 13 from forming an angle at the support base plate 3 at the top of the side column 6, thereby avoiding stress concentration in the component steel cable.
[0028] Reference Figure 1 , Figure 3 and Figure 4 The force-applying component is a jack, which facilitates applying force to the end of the finished rigging 9. A pair of side columns 6 have rotating grooves 1001 through their side walls. The rotating seat 10 includes a pin 103 set inside the rotating groove 1001. A pair of side plates 102 are symmetrically arranged on the side wall of the pin 103 and placed on both sides of the pair of support plates 1. An end plate 101 is set between the pair of side plates 102. This design facilitates the rotation of the rotating pin 103 inside the rotating groove 1001, while driving the side plates 102 and the end plate 101 to rotate. The pin 103, side plates 102, and end plates 101 are fixedly connected at the connection point. When the rotating seat 10 is damaged, it is easy to replace and easy to connect and assemble with the rotating groove 1001.
[0029] Reference Figure 5 , Figure 6 and Figure 7 The finished rigging 9 includes a clamp anchor 93 set on the side wall of the end plate 101. A jacking pipe 92 is set on the side of the clamp anchor 93 away from the end plate 101. An extrusion anchor 91 is set on the side wall of the jacking pipe 92, which improves the rationality of the design.
[0030] Reference Figure 4 and Figure 5The end plate 101 has a first through hole 1011 on its side wall, and the pin 103 has a second through hole 1031 on its side wall. The component steel cable 13 passes through the extrusion anchor 91, the jacking pipe 92, the clamp anchor 93, the first through hole 1011, the second through hole 1031, and a pair of support plates 1 in sequence. The axis of the first through hole 1011 and the axis of the second through hole 1031 coincide. This design facilitates the component steel cable 13 to pass through the end plate 101 and the pin 103 through the first through hole 1011 and the second through hole 1031.
[0031] Reference Figure 1 and Figure 3 A first reinforcing plate 2 is symmetrically arranged between a pair of support plates 1 and support base plate 3, a second reinforcing plate 4 is symmetrically arranged between a pair of support plates 1 and support base plate 3, and a partition plate 11 is symmetrically arranged between a pair of support plates 1 above the rotating groove 1001. This design improves the stability of the connection, strengthens the connection between them, and improves the reliability during use.
[0032] Reference Figure 1 , Figure 3 and Figure 5 A second limiting plate 12 is provided between the tops of a pair of support plates 1, and an inclined surface 1002 is provided on the side wall of the pair of support plates 1. A first limiting plate 8 that fits against the inclined surface 1002 is provided between the pair of support plates 1 and the support base plate 3. This design uses the first limiting plate 8 to limit the downward rotation angle of the rotating seat 10, and uses the second limiting plate 12 to limit the upward rotation angle of the rotating seat 10.
[0033] Reference Figure 1 and Figure 2 A pair of column ear plates 5 are symmetrically arranged on the side wall of the side column 6. Each pair of column ear plates 5 has a connecting hole 51 on its side wall. This design facilitates the connection and fixation of the external tie rod to the support ear plates 7 on the side column 6 by means of U-bolts.
[0034] Reference Figure 1 , Figure 2 and Figure 3 The side wall of the side column 6 has a through support groove 61 that is connected to the top of the side column 6. The support groove 61 has a support ear plate 7 for supporting the base plate 3. The side wall of the support ear plate 7 has an installation hole 71 that is placed below the finished rigging 9. This design improves the stability of supporting the base plate 3 by using the support ear plate 7. The installation hole 71 facilitates the connection of external tie rods (cables) to tension and fix the support ear plates 7 on the side column 6 with U bolts.
[0035] Reference Figures 1-7As an embodiment of this utility model: when it is necessary to adjust the included angle between the component steel cable and the side column 6, the component steel cable 13 first passes through the compression anchor 91, the jacking pipe 92, the clamp anchor 93, the first through hole 1011, the second through hole 1031, and a pair of support plates 1 in sequence. The jacking pipe 92 and the compression anchor 91 are respectively fitted onto the end of the component steel cable 13. Then, the compression anchor 91 is locked with a tool, and the compression anchor is withdrawn. In actual application, both ends of the component steel cable 13 have flexible support side column cable connection nodes with adjustable angles. Then, professional construction personnel apply force to the end of the finished cable 9 by using the force-applying component jack. The jack is at the clamp anchor 9 The component steel cable 13 is tensioned to the design value at three points, thus pre-tensioning the component steel cable 13 and generating prestress in it. With tension, the flexible component steel cable 13 becomes a rigid straight line. At the same time, the rotating seat 10 automatically adjusts its angle as the component steel cable 13 is tightened, thereby adjusting the angle between the rotating seat 10, the finished rigging 9, the component steel cable 13, and the side column 6 according to different terrains. This ensures that the component steel cable 13, the rotating seat 10, and the finished rigging 9 always remain in a straight line, preventing the component steel cable 13 from forming an angle at the support base plate 3 at the top of the side column 6, thus avoiding stress concentration in the component steel cable.
